Hey guys I brought some clen for a friend, its powder clen Jurox brand. It was all seeled so that reassured me that its legit. However my friend has been taking about a teaspoon of it a day and not noticing any effects. Ive never used it before but I tried half a teaspoon just to see what he was on about and I didnt notice any increased heart rate at all. Could this stuff be fake? Im thinking it is but im confused cos it was sealed. Also how much to take if its powdered?
